  1. PORendering and process same form twice in Zend Framework 2?
    text
    copied!<p>I have a requirement of rendering and processing the same form again if user check a select box. I looked into form collections but it didn't exactly access my problem because I don't need to render a set of fields instead my requirement is to render the complete form again. So what I added another function getClone($prefix) to get the clone of form which returns me the clone of form object after adding a prefix in the name of form. Like this</p> <pre><code>&lt;?php namespace Company\Form; use Zend\Form\Form; use Zend\InputFilter\Factory as InputFactory; use Zend\InputFilter\InputFilter; use Zend\InputFilter\InputFilterAwareInterface; use Zend\InputFilter\InputFilterInterface; class CompanyAddress extends Form implements InputFilterAwareInterface { protected $inputFilter; public function __construct($countries, $name = 'null') { parent::__construct('company_address'); $this-&gt;setAttribute('method', 'post'); $this-&gt;setAttribute('id', 'company_address'); $this-&gt;add(array( 'name' =&gt; 'street_1', 'attributes' =&gt; array( 'id' =&gt; 'street_1', 'type' =&gt; 'text', ), 'options' =&gt; array( 'label' =&gt; 'Street *', ) )); $this-&gt;add(array( 'name' =&gt; 'street_2', 'attributes' =&gt; array( 'id' =&gt; 'street_2', 'type' =&gt; 'text', ), 'options' =&gt; array( 'label' =&gt; 'Street 2', ) )); $this-&gt;add(array( 'name' =&gt; 'country_id', 'type' =&gt; 'Zend\Form\Element\Select', 'attributes' =&gt; array( 'id' =&gt; 'country_id', ), 'options' =&gt; array( 'label' =&gt; 'Country', 'value_options' =&gt; $countries ) )); $this-&gt;add(array( 'name' =&gt; 'city_id', 'type' =&gt; 'Zend\Form\Element\Select', 'attributes' =&gt; array( 'id' =&gt; 'city_id', ), 'options' =&gt; array( 'label' =&gt; 'City ', 'value_options' =&gt; array() ) )); $this-&gt;add(array( 'name' =&gt; 'zip', 'attributes' =&gt; array( 'id' =&gt; 'zip', 'type' =&gt; 'text', ), 'options' =&gt; array( 'label' =&gt; 'ZIP', 'value_options' =&gt; array() ) )); $this-&gt;add(array( 'name' =&gt; 'address_type', 'type' =&gt; 'Zend\Form\Element\Select', 'attributes' =&gt; array( 'id' =&gt; 'zip', ), 'options' =&gt; array( 'label' =&gt; 'Type', 'value_options' =&gt; array( '' =&gt; 'Select Type', 'default' =&gt; 'Default', 'invoice' =&gt; 'Invoice', 'both' =&gt; 'Both', ) ) )); } public function getClone($prefix){ $form = clone $this; foreach($form-&gt;getElements() as $element){ $name = $element-&gt;getName(); $element-&gt;setName("$prefix[$name]"); } return $form; } public function getInputFilter() { if (!$this-&gt;inputFilter) { $inputFilter = new InputFilter(); $factory = new InputFactory(); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'street_1', 'required' =&gt; true, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( array( 'name' =&gt; 'NotEmpty', 'options' =&gt; array('message' =&gt; 'Street cannot be empty'), ), ), ))); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'street_2', 'required' =&gt; false, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( ), ))); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'city_id', 'required' =&gt; true, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( array( 'name' =&gt; 'NotEmpty', 'options' =&gt; array('message' =&gt; 'City cannot be empty'), ), ), ))); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'country_id', 'required' =&gt; true, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( array( 'name' =&gt; 'NotEmpty', 'options' =&gt; array('message' =&gt; 'Country cannot be empty'), ), ), ))); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'zip', 'required' =&gt; true, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( array( 'name' =&gt; 'NotEmpty', 'options' =&gt; array('message' =&gt; 'ZIP cannot be empty'), ), ), ))); $inputFilter-&gt;add($factory-&gt;createInput(array( 'name' =&gt; 'address_type', 'required' =&gt; true, 'filters' =&gt; array( array('name' =&gt; 'StripTags'), array('name' =&gt; 'StringTrim'), ), 'validators' =&gt; array( array( 'name' =&gt; 'NotEmpty', 'options' =&gt; array('message' =&gt; 'Address Type cannot be empty'), ), ), ))); $this-&gt;inputFilter = $inputFilter; } return $this-&gt;inputFilter; } } </code></pre> <p>and than in my action I did this </p> <pre><code>public function testAction() { $countries = $this-&gt;getServiceLocator()-&gt;get('Country')-&gt;getSelect(); $companyAddressForm = new CompanyAddressForm($countries); $clone = $companyAddressForm-&gt;getClone('address2'); if($this-&gt;request-&gt;isPost()){ $data = $this-&gt;request-&gt;getPost(); $companyAddressForm-&gt;setData($data); $clone-&gt;setData($data['address2']); $isFormOneValid = $companyAddressForm-&gt;isValid(); //$isFormTwoValid = $clone-&gt;isValid(); } $view = new ViewModel(); $view-&gt;companyAddressForm = $companyAddressForm; $view-&gt;clone = $clone; return $view; } </code></pre> <p>This is working as I expected it to work, forms are rendering and validating correctly, I want to know whether it is a correct way or a hack?</p>
